GEORGE H. FLINTI-IAIVI AND PHILIP QT. GILSTRAP, OF TOPEA, KANSAS; SAID FLINTHAM ASSIGNOR OF HIS RIGHT TO MARY CRAWFORD FLINTHAM.

MIXER.

Specification of Letters Patent.

Patented Feb. 10, 1920.

Application filed July 5, 1918. Serial` No. 243,401.

To all whom t may concern:

Be it knownthat we, GEORGE l-l. FLINT- HAM and .Prrinirl GILSTRAP, citizens of the United States of America, residing l at Topel{a,vin the county of Shawnee and State of Kansas, have invented new and useful Improvements in Mixers, of which the following is a specification.

This invention has reference generally to improvements-in gas engines, and more particularly relates to a mixer.

lt is the principal aim and object of the present invention to provide a device of the above mentioned character designed to be inserted in the manifold of the gas engine between the carbureter and the engine for acting on the gases which are drawn through the manifold for breaking the mixture into small globules, to provide a proper mixture at the time it enters the engine for consequently increasing efficiency of the engine when in operation.

More particularly the present invention contemplates the provision of a device of the above mentioned character designed to be actuated by the suction through the manifold for acting upon the incoming charge, while the construction is such that it will not obstruct the passage of the mixture through the manifold.

It is a more specific object of the present invention to provide a -device of the above mentioned character embodying a frame in which is mounted a small spindle designed to rotatably support a series of fans each of which are rotatable by the suction so that the blades thereof will act upon the mixture to produce a substantially dry gas at the time it enters the cylinder so as to obviate the accumulation of carbon in the engine and at the same time reduce the consumption of gasolene.

Among the other aims and objects of this invention may be recited the provision of a device of the character described with a view to compactness, and in which the number of parts are few, the construction simple andthe cost of production low and the efficiency high.

Other improvements and novel details in the construction and arrangement of the various parts of the apparatus will be brought out more in detail in the description to follow, which for a clear understanding of the invention should be considered in connection with the accompanying drawings forming a part thereof, and herein is disclosed for the purpose of illustration a convenient and satisfactory embodiment of the invention. lt is to be noted in this connection that minor changes in the construction and arrangement of parts may be made without departing from the principle of operation of the various parts.-

Ilhe invention is clearly illustrated in the accompanying drawings, in which Figure 1 is a vertical sectional detail showing the invention applied and positioned in the manifold.

Fig. 2 is a perspective detail view of the device detached.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.l

Referring now, more particularly, to the accompanying drawings there is illustrated a carbureter 1 from which leads a conducting pipe 2 terminating in a flange 3 which is designed to be secured to the iianged end 4. of the manifold 5 of the engine 6 through the instrumentality of bolts 7, while frictionally supported in the manifold 5 near the flanges 3 and 4 is the improved mixer generally designated 8.

ln the present instance the mixer consists of a frame generally designated 9, constructed from a single piece of resilient strap like metal, and this strap is bent into a substantially inverted U-shaped configuration comprising spaced side arms 10 and an intermediate portion 11 having an opening 12 therein. The free terminal of one arm is bent inwardly and horizontally forming a supporting arm 13 which in turn is provided with an opening 14, while j ournaled in the opposed openings 12 and 14 are the reduced ends of the spindle 15. Carried at spaced intervalsv on the spindle 15 are vertical series of fans 16 each of which consists of a hub portion 17 and opposed blades 18.

Arcuate wings 19 are secured to the outer faces of the arms 10 at opposite points by fasteners 2O and are designed to frictionally engage the inner surface of the manifold under the tension of the arms 10 so as to retain the device in position.

In operation, the frame together with the blades being disposed within the manifold pipe in a manner so as not to obstruct the passages of the mixture through the manifold pipe, the suction produced by the operation of the engine draws the mixture through the pipe and at the same time rotates the spindle l5 and fans 16, the blades 18 of which act upon the mixture for breaking the gasolene up into very small globules to produce a substantially dry gas which besides causing a saving of fuel reduces the accumulation of carbon inthe engine and thus assures of an effective operation of the en ine.

t is thought in View of the foregoing description that a further detailed description of the operation of the invention is entirely unnecessary. Likewise it is believed that the advantages of the invention will be readily apparent.

As many changes could be made in the above construction and many apparently widely diierent embodiments of this invention could be made without departing from the scope thereof it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limited sense. It is also to be understood that the language used in the following claim is intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

l/Vhat is claimed is A mixer consisting of an open frame constructed of resilient strap metal, the frame having a pair of spaced side arms, an intermediate portion connecting the side arms and a supporting arm interned from one of the side arms and having its extremity a space from the extremity of the other side arm, a spindle having reduced ends which are journaled in the intermediate portion and supporting arm of the frame, a plurality of blades carried by the spindle, and arcuate wings carried by the two side arms, the said arcuate wings straddling the side arms and being secured thereto, whereby the frame may be positioned in the fuel intake pipe of a vehicle engine and maintain frictionally therein but positively holding the spindle axially alined to said pipe for the beating of the fuel for the purpose specified.

In testimony whereof we aflix our signatures.
